' G. HEINTZE MACHINE FOR DRAWING WOOL OR OTHER TEXTILE FIBER MATERIALS Filed May ll 1927 the gills from the wool fleece, a stream of and Fig. 2 shows diagrammatically the further treatment of the wool-fleece afterhav ing left the machine shewn in Fig. 1. A

a, Fig. 1, is the Washing machine proper filled with any suitable liquid (soap-suds or other extractive means) up to the dotted and dashed line. b is an endless. band to which the wool deprived of grease in the extracting apparatus, for instance of 'system Malard, or in any other suitable manner is fed to be carried to the first drawing-gill-set 0. An endless rubber-band d is arranged in rear of said gill-set 0 and serves to feed the wool-fleece drawn in the first gill-set 0 to a doubling device 7, after having passed through a pair of squeezing cylinders ,e. Said doubling device is diagrammatically shown and consists of aknown device for laying the fleece in longitudinal direction and for supplying acontinuous fleece. The doubled fleece having left the laying device enters into a second drawing-gill-set 0,. Ac-

cording to want, three or four of such draw ing-gill-sets arranged in series, and between each two gill-sets pairs of squeezing-cylinders e, and e, and doubling devices f and f and so forth may be provided.

During the drawing procedure effected within the liquid, the burs and other vegetable impurities are retained in the gillfield. The fibers or hairs entangling said burs are drawn in a forward and backward.

direction so that the burs and particles are freed-and remain back on the wool fleece,

effect of the washing-procedure and to remove the vegetable impurities freed between water may be passed in a vertical or nearly the gill-field. This can be done, for instance, in such a manner that either a stream of water is directly passed through the gills from above in a downward direction or vice versa by'a pump, represented generally at p,

or the liquid is fed in a cycle through the gill-field in the direction indicated by arrows. The liquid is purified by passingit of squeezing-cylinders 6 and spread in a thin layer can be fed through rollers h, h k h,

, arranged, for instance, within a chamber, as

diagrammatically shown in Fig. 2. A stream of warm air, 9, can be blown through said rollers for the purpose of drying the fleece. Without any regard to the wool becoming electric later on, said drying proce-' dure can be continued to such a degree that inders '70,, 10,, k by another intense stream of air. By the addition of a finely atomized softening material to this stream of air Z the latter can perform the softening of the ribbon or silver and be kept so moist that the wool is again brought to that degree of moisture which is necessary for its further treatment. I

The wool-fleece drawn and cleaned inthe manner described can be fed to the combingmachine thus dispensing with sets of carding-machines, or it may be used also as a fine roving for certain requirements of long wool spin ng or card-yarn-spinning. I

, What I claim is: i

1 A machine .for drawing wool and other textile fiber materials in which the saidmaterials are drawn within a washing vessel, said. machine comprising 'a plurality, of drawing-gill sets arranged. inseries and having. their working surfaces situated below 7 the level of the liquid in said vessel.

. 2. A machine for drawingwool and other textile fiber materialsin whichthe said mas terials are drawn within awashing vessel, said mach ne comprislng a plurality of drawing-gill sets arranged in series and having their working surfaces. situated below the level of liquid in said vessel, and means from which they can afterwards be removed l by burring-willows- To get a more intense for causingaflow of liquid in a substantially vertical direction through the material in the drawing-gill sets, a l r 3. A machine for-drawing wool and other textilefiber materials in which the said'ma terials are drawn within a washing Vessel, vertical direction through said fleece held in r said machine comprising a plurality of drawing-gillsets arranged in series and havingtheir working surfaces situated below the level of liquid in said vessel, and means arranged between adjacent drawing-gill sets fordoubling and laying the material as it passes from one drawing-gill set to the next.

4. A machine for drawing wool and other textile fiber materials in which the said ma terials aredrawn within awashing vessel,

drawing-gill sets arranged in series and hav ing their working surfaces situated below the level of liquid in said vessel, means for causing a flow ofliquid in a substantially vertical direction through the material in said ,machine comprising a plurality of the drawing-gill sets, and means arranged between adjacent drawing-gill sets for doubling and laying the material as it. passes from one drawing-gill set to the next.

5. A machine for drawing wooland other textile fiber materials in whichthe said materials are drawn within awashing vessel, said machine comprising av plurality of drawing-gill sets arranged in series and having their working surfaces situated below the level of liquid in said vessel, means adj a.-

cent the last said drawing-gill set for drying and flattening the material, and rolls adjacent the drying and flattening means for disintegrating burs in the material.

6.

In testimony, that I claim the foregoing as my invention, I have signed my name this 10th day of March, 1928.
